environment: Add adjustAnimationTime() helper

As we currently use Tweener for all animations, we have a single place
for hooking up the enable-animations and slow-down-factor settings.
However that will no longer hold true when we'll start to use Clutter's
built-in animation facilities, so add a small helper function that
applies the necessary adjustments.
